Fluid flow momentum equation
WebA momentum-forcing term is added to the Navier–Stokes equation in order to impose the no-slip boundary condition on the wavy wall. Parametric study is carried out to analyze the fluid flow characteristics by varying wave geometry factor (WG Factor) of crest–crest (CC Model) wavy wall configurations for Reynolds number ranging from 10 to 50. In words, this previous equation states that Total Forces = Body Forces + Pressure Forces + Viscous Forces = Time rate of change of momentum inside from any unsteadiness in the flow + Net flow of momentum out of per unit time. Equation 10 is the momentum equation in its integral form.

According to this idea, the density is constant when the pressure is constant. The mathematical interpretation of the pressure gradient can be ...
WebThus for laminar flow of a Newtonian fluid in a pipe the momentum flow rate is greater by a factor of 4/3 than it would be if the same fluid with the same mass flow rate had a uniform velocity. This difference is analogous to the different values of α in Bernoulli's equation ( equation 1.14 ).
